Why do big cities need more water?
Answers
Answer:
Rapid population growth, urbanization and economic development lead to growing pressure on water resources in urban areas. The demand for water is rising constantly. With water demand exceeding water supplies, water shortage has become more prominent in many cities in both the developed and developing world.
Cities face rising water and sanitation demands and problems such as pollution and overexploitation. Especially the large urban population living in slums often lack access to safe water and sanitation services.
Cities rely on water resources to provide services to their residents that can go unnoticed. When we think about water in our daily lives we often think about drinking water, taking a shower, brushing our teeth or watering the lawn. Water is necessary for survival, hygiene and to maintain our yards, but cities also utilize water supplies for everyday use that benefit their community in many ways we never think about.
Fire hydrants include important infrastructure necessary to provide residents with the fire flows as required by regulations to fight fire. The City of Riverside, which has its own fire department, receives the water used for firefighting from the same sources as drinking water. The water used for firefighting is not recycled water, it is in fact potable drinking water.
While some fire trucks do hold water, many variables affect if and when water from a hydrant is needed to fight fire. Hydrants pull water from the same water supply that residents receive in their homes. Hydrants are able to provide pressurized water through the use of fire engines to fight fire. Hydrants provide a life-saving tool when needed and without water they would not be effective.
Cities also utilize water for street cleaning services. Keeping roads clean and maintained preserves the appearance of communities. Street cleaning is a service that may go unobserved by residents, however it is not only necessary for the visible appearance, but also because it eliminates trash and debris that can often end up in the storm drains. Water used in street cleaning services can come from recycled or potable drinking water.
